i Moron Application filed September 15,1926. Serial No. 135,603.

. This invention is an apparatus for utilizing thev torce ot 'water tor the application or storage o t' energy, and one object or' the invention is to provide a simple apparatus which may be advantageously employed `,wherever there is a natural fall of water.

Anotherobject oi the invention is to provide a hydraulic motor ot such construct-ion that .a relatively large volume of power `may be developed from a relatively small flow or j tall of water, and anOtherbb-jeCt `of the invention` is to provide anV apparatus which will operate automatically as long as the flow of water is continued. Other objects "ofthe invention will appear incidentally in -.the course of the following description, and the invention resides in certain novel features which Willbe particularly defined inV fthe appended claims. i

In the accompanying drawings Figure 1 is a plan View of a motor constructed in accordance with 'the' present in- ,vent1on;

Fig. 2 is a vertical section on the line 2-2 ot Fig. 1;

F ig.` 3 is a vertical section on the line 3-3 ot Fig. 1,V and i Fig. 4 is a detail perspective view of the reversing lever. i

vIn carryingv outV my invention, I employ a caisson or housinfr structure 1 of concrete which may be built up accordingto any 'method now generally practiced or. hereafter' approved. l The caisson or foundationor housing is so arranged as to provide a large j central working chamber 2 Iand a` plurality ot auxiliary chambers 3 arranged along the sides `of the said working chamber. At one end of the caisson is arranged a tanlr'or reservoir 4 into which the water 1s led from the source of supply throu h a'pipe 'which iis equipped with a cut-o` approved form so that the iow of the water valve 6 ot any may be regulated or cut off entirely when desired. `From the reservolr or receiving tank v4, an outlet pipe 7 extends to the bottom of the working chamber 2 so that the water -will be delivered at the bottom of the chamber to act upon a plunger 8 mounted therein.

The plunger 8 may be constructed ot any .suitable material and its horizontal areais slightly lessthan the area of the working chamber 2 so that `the plunger may move up and down within the chamber without damaging contact withthe walls 4ot the same. Upon they end walls ofthe working` chamber 2 at any convenient or preferred 'p manner if desired. This post rises to a point'above the top of the caisson and its upper closedv end spans one end 'ofV a lever 13 which is fulcrumed between its ends upon a. bracket 14 securedk upon the caisson adjacent the tank 4, as will be understood. The outer` end of the lever 13 pla s within a bail or slotted post 15 carrying a: vall valve V16v at its lower end, which valve is arranged' to seat upon the upper end of the supply pipe 7 and cut-,ott the flow thereto at intervals in the operation ot the apparatus. TheV bracket 14 projects aboveA the fulcrum of the lever 13 and in thelupper end of said bracketis fulcrumed a latch or rocking arm 17 which extends to bothsides of the bracket and has its ends down turned, as shown at' 18, and

ing upwardly from` this latch and arranged at a right angle to the length 'of the latch v'is a central4 arm 19 carrying a weight20 at its upper end.l

It will be understood that the force of the water entering thejchamber 2 elevates the plunger 8 and the postfll, of course, moves upwardly with the plunger. As the plunger reaches the top of the Working chamber 2 `the top .of the plunger willr impingeagainst the adjacent overhanging end ofthe lever 13 `and will rock the rlever .to the position il- .lustrated in Figs. 2 and4. The bail 15 and valve 16 will, consequently, thenbe unsupp ,ported and will drop by gravity onto the valve seat at the upper end of the pipe 7 so that the furtherflow of water into the workot the post 1v1 will impinge against the adjacentend of the lever lfand reverse vthe position of the as it swings to the positiono-pposite that illustrated. Vhen the lever 13 is rocked to the position illustratedV in Figs. 2 and, 4, the end of the latch 17 which vis then in contact with the lever will, of course, be

Secured upon the plunger and .adaptedl to bear upon the lever'4 173. Extendfing chamber` will be ,cut oit. The lweight f 4of the plunger thenot course, causes` it to d'ro'p,r and eventually the upper closed end V arts, the lever engaging ,the top of the ball 15 and lifting the valve.

vin and having a piston rod 26 extending vthrough the upper head of the cylinder and `moved upwardly so that the latch will also be krocked about its pivot and the weight.

20 will be carried to the opposite side of the pivot and will, consequently, act tol maintain the latch in the position illustrated with its outer end in contact with the outer end portion oi' the lever 13. The valveV 1GV will,:V consequently, be permitted to remain seated until the plunger 8 has completed its down stroke and the lever I3 reversed in the inan-V ner described. Likewise after the lever has been reversed,.the valve will be held unseated until the upstroke of the plunger hasV been completed. n

To provide for the discharge of water from the caisson after the plunger has been raised, a Siphon exhaust 2l is arranged at the vend of the working chamber oppositethe supply pipeV 7. This Siphon is in the form of an inverted U-shaped conduit with one end in communication wtih the lower portion of the Vworking chamber 2 and its opposite end connected with an outflow pipe or carried oli' to any other point of discharge. In the top of the siphon or the upper bend oi the Usshaped conduit is provided a vent for'any air which may be trapped therein, lthe said vent including ai short pipe 22 eX tending fromthe bend above the caisson and equipped with an outwardlyopening valve 23. The level of water inV the receiving branch of the Siphon will, of course, beat least as high as they level of the water in the Vseated and such air permitted to escape so that the siphon will operate very veiticientlyV to eec't discharge of the water and-aid the descent of the plunger.

It will `be understood that the apparatus maybe designed in such proportions that the reciprocation or the plunger may be device, however, is particularly adapted to create a supply of compressed air for use where and Vwhen needed, and I have illustrated means whereby it'will be utilized for such purpose.v In each of the chambers 3 is located a cylinder 24 which is of air-tight construction and substantial so as to resist high pressure. Fitted in each cylinder 24 is a piston 25 mounted to reciprocate theresecured to a cross bar27 which is connected iirmly withv the plunger 8 through a frame consisting of uprights 2S and bracing beams 29. 'It will be readily noted, upon reference to Figs. l and 3, that each cross bar 27 is :connected to two piston rods and that theV uprightsV are arranged adjacent the sides of Vthe working chamber 2 so that they maybe guidedthereby. It will also be noted that all the pistons are operated` synchronously and, consequently the conditionsrin any o ne cylinder at any time are the ksame as the working conditionsV in all the other cylinders. VExtending vertically within each chamber 3 are intake pipes 30 and outlet pipes 3l which communicate at their lower yends with thelower'ends of the cylinder in son with anV inwardly opening check valve 32 of any known or approved construction whereby air maybe drawn in'through the said pipe but will be prevented from escaping therefrom and the outlet pipe 31 is eX- tended to Aany suitable compressed air reservoir (not shown). In the top or upper head of each cylinderf24 are fittedl the ends of intake pipes 33'and outlet pipes 34, the intake pipe being equipped 'with an inwardly opening check valve' 35 and the outlet pipe beingextended to' the compressed air reservoir. l y

'It will now be seen that the pistons 25 through theirV connections with the plunger 8 move simultaneously in the same direction as the plunger; On the up-stroke, air

will be Vdrawn into the cylinders through 'the Vpistons 25'will likewise be reversedV and they will then move downwardly Vwithin their respective cylindersso Vthat ,the an below the several pistons will ,be compressed i and'foreed` out through'the outlet pipes 31. This operation will obviously be continued aslong as the supply of water is maintainedV through the main inlet 'pipe 5, and the supply jo compressedv air` will thus be main-Y tained withoutlrequiring the services of a utilized directly to operate machinery. The

y claim: Y Y
